SPECIFICATION forming part of Letters Patent No. 585,987, dated July 6, 1897. Application filed February 24, 1897. Serial No. 624,893- (No model.)

struction of singletree coupling or clamp whereby I am enabled to apply the same readily and expeditiously to a singletree without piercing the latter and thereby weakening the same.

It also consists of a novel construction of shackle or clevis which is attached to the coupling or clamp in such manner that all oscillation or movement thereof relative to invention, the same being shown in detached position. Fig. 2 represents a similar view of the coupling, showing the shackle or clevis in detached position. Fig. 3 represents an end view of the coupling. Fig. 4 represents a section 011 line a; .90, Fig. 3. Fig. 5 represents a front elevation of a doubletree and singletree, showing the manner of attaching the clamp or coupling to the latter and of making connections from said clamp to the doubletree.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a singletree clamp or coupling, the same consisting of the members 13 and (1,which are of circular or other desired shape, so as to readily engage and conform to the contour of the singletree, each of said members being provided with ears D, whereby they are held in juxtaposition at their lower portion by a bolt E or other suitable fastening device.

F designates a plurality of lugs which are attached to the member 0 oppositely to the ears D, between which is located, when the parts are assembled, the lug G, which is at tached to the member B,

H designates a shackle or clevis which is that when the parts are assembled and the clevis H is in position its extremities L enter the openings M, and all the parts are held in assembled position by means of the bolt N or other suitable fastening device, attention being further called to the fact that the clevis H is positively locked in position with respect to the coupling or clamp A and is incapable of independent swinging or oscillation relative thereto.

The manner of making the connections between the singletree and doubletree will be understood from Fig. 5, in which P designates a doubletree and R a singletree which has the coupling A attached thereto, the clevis H thereof being engagedby a suitable hook or similar device Q, attached to the doubletree.

Especial emphasis is laid upon the fact that in the employment of my invention no necessity exists for piercing the wood of the singletree, and thereby weakin g the same, and that the parts constituting the clamp can be readily and expeditiously assembled or disconnected, according to requirements.

It will of course be evident that changes may be made by those skilledin the art which will come within the scope of my invention, and I do not, therefore, desire to be limited in every instance to the exact construction I have herein shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A singletree-coupling having sections provided with lugs having openings, a clevis with openings in its limbs, and a bolt in the openings of said lugs and clevis, said sections having openings adjacent to said lugs to receive the angular ends of said limbs.

2. A singletree-coupling consisting of two sections having lugs for connecting said sections and ears with means for locking said sections in closed condition, aclevis provided with angular ends located in openings in said sections, and a bolt or fastening device passing through openings in the ends of said clevis and through said lugs.

3. A singletree-coupling composed of sections, ears attached to said sections, means for holding said ears in juxtaposition, lugs oppositely located with respect'to said ears, the upper portions of said sections adjacent to said lugs having openings therein, a clevis having openings common to said lugs and its extremities adapted to enter the openings in said sect-ions whereby independent oscillation or movement of the elevis relative to said coupling is prevented.
